I was on Fiberglass , Epoxy , Composites, Carbon Fiber - U.S. Composites, Inc. , and I noticed epoxy resin is $100/gal, whereas polyester resin is $35/gal at the auto parts store. I'm tempted to just use the polyester because I read on the internet it's easier for a beginner to work with. Downsides of polyester are that it eats styrofoam, it's heavier and thicker than an epoxy composite of the same strength, and it gives off more VOC's during curing.
